This invention relates to a method of preparing edible products and more particularly to prebahed dough products for the reception of sandwich fillers, although certain features thereof may be employed with equal advantage for other purposes.

contemplates more especially the novel processing of pre-balced dough products to' serve as an envelope for any suitable sandwich filler, thereby enabling the consumption thereof without resort to a dish, fork or other commonly employed eating implement.

liiandwich luncheons are becoming increasingly popular but an objectionable feature is the required handling during the consumption thereof to the end that the filler too often is displaced from the sandwich for accidental lodgernent on the individuals garment. flandwich fillers usually attempt to confine various forms of garnishes and other juicy appetizers which are incapable of retention without undue care and attentive handling. lhis precludes the preparation and consumption of ver and appetizing edibles for sandwic consumption with known methcds, and for that reason sandwiches have ordinarily been served with dry and rigid fillers which are not altogether desirable.

Moreover, standard sandwiches of uniform taste and preparation are impossible with the customary methods, and for that reason sandwich luncheons vary within a wide range without any possible pro-expectancy at the instance of the purchaser. Standardized sandwich luncheons have not heretofore been lrnown nor thought possible of attainment; however, this is readily possible with the teachings of the present invention to the end that a uniform heated sandwich luncheon can be dispensed over the counter without quality, taste or other variations throughout an almost universal market irrespective of geographical limitations.

With the teachingsof the instant invention, the objectionable features of the customary sandwich are entirely overcome, and improved edibles are capable of preparation with enhanced taste and facility to consume without resort to dishes, forks or other commonly employed eating implements. Moreflled October 27, 1927. This application filed February over, most any type of filler may be employed with juicy or liquid taste imparting ing pro-baked edibles for sandwich purposes.

Another object is to provide a process of preparing edible sandwiches in a manner which improves the taste-and handling characteristics thereof.

Another object is to process edible sandwiches in a manner so as to afiord the prepa ration of a product having uniform taste, size and qua ity characteristics with little variations to the end of definite standardization.

Still another object is to provide a method of providing a sandwich having a tasty filler envelope to enable consumption without resort to dishes, forks or other commonly em ployed eating implements. I

it further object is the provision of a process of preparing re-baked edibles to the end of providing a ller confining cavity therein for enhancing the taste qualities and corn sumption characteristics thereof.

A still further object is to provide an improved method of preparin sandwiches hav ing a totally confinin edi le envelope with an interiorly toasted ller retaining cavity.

Still a further object is the provision of a method of preparing pro-baked dough edibles to serve as an envelope for sandwich fillers of any physical consistency or characteristics without subjecting an individual to arment soiling or requiring resort to dishes, orks or other commonly em loyed eating implements.

An additional obyect is to provide a recess of preparing novel and improved san wiches which can be commercially served over the counter and held in the fingers for convenient consumption without resort to auxiliary eatin implements.

her objects and advantages will appear from the following'description of an illustrative embodiment of the present invention.

In the drawings: Fi re 1 is a perspective view of a prebake dough roduct showing the slit therein for a cavity .ormation.

Figure 2 is a perspective view of the ounshown in Figure 1 subsequent to the formation of the cavity therein for the reception of an edible filler such as cheese, frankfurters or meats in the presence or absence of garnish such as lettuce and similar appetizers, parts thereof being broken away to clarify the showing.

Fi re 3 is a front view in elevation of a toasting device which serves to form the cavity for confining the edible sandwich fillers.

Figure 4 is an end view of the device shown in Figure 3, the pre-baked dough article being shown in association therewith in dotted outline.

A process of preparing edibles selected for illustrating the teachings of the present invention comprises the processing of edible substances such as pre-baked dough products so as to serve as an envelope for fully confining sandwich fillers of any desired physical consistency and characteristics conducive to a tasty and appetizing product for consumption purposes. No particular apparatus 7 is essential, but to clarify the disclosure reference is had to the illustrated structure selected merely for illustration. The pre-baked dough product may be of any form or possess any desired edible characteristic, t ese being of standard variety or specially prepared for the purpose, as commercial practlce may dictate.

The preferable form of the edible sandwich filler envelope comprises a pro-baked dough product such as a bun or roll havin a crusted exterior 10 with a yieldable doug 11 shaped to present an elongated preferably flat configuration. The bun is rst severed slit 13 which continues through the interior along the length thereof to. the region approaching the opposite end 14, care being taken not to pierce or rupture the-cruste exterior 10 except in the original region of insertion in the end 12 thereof so as to form a pocket enclosed on all sides except for the mouth thereof constituting the region of initial severance or piercin The t sides of the pocket originating rom the slit 13 are interior.

along one end 12 thereof to present a linear then separated as far as practical so as to' ing character thereof, render such form retainin and improve the taste characteristics thereoi.

In order to fu'rtherimprove the taste characteristics of the sandwich prepared in this manner, the interior walls of the cavity 15 are preferably heated for a period suflicient to effect the toasting thereof. This lends crispness to the cavity walls 15 and imparts the desired rigidity thereto for a more advantageousand successful incorporation of the sandwich filler, and further results in a more tasty edible to the end that it may be consumed without resort to any dishes, forks or other commonly employed eating implements. The juices of the filler, garnish or appetizer cannot possibly be displaced therefrom for accidental lodgement on the individual to the end of precluding soiled garments and other inconveniences usually attendant with the consumption of ordinary sandwiches. The edible may be prepared and the process performed with a device comprising, in this instance, a suitable base 16 stamped or otherwise shaped fromssheet material to pre-. sent a supporting surface 17. The surface 17 supports a member 18 which comprises, in this instance, an elongated s ike having flat inclined sides 19 and 20 which converge to define anangular edge 21 with the diverging ends flanged as at 22 for attached support on the base surface 17 in any suitable manner as commercial practice may dictate. I In consequence thereof, the-bun 10 may. be originally ierced with a lmife or other severing -imp ement to present an initial slit 13 which is placedvover the edge 21 of the cavity forming member 18 for. telescopic association responsive to the continued displacement through the interior of the bun 10 alonglthe length thereof to the end of forming t e cavity 15 by the displacement of the dough 11 outwardly into the bod of the bun 10. The manual displacement o the bun 10 over the cavity forming member 18.continues to'a point reaching the opposite end region l'without piercing or rupturing the exterior of the bun 10 except-in the initial region 13. I

Simultaneous with the formation of the cavity 15 by the displacement of the bun 10 over the forming member 18, heat is su plied from any suitable source such as an e ectric heating element 23of an approved or suit- 12 able construction. The eating element 23 is preferably confined between the sides 19 and 20 of the cavity forming member 18 so i as to elevate the temperature of the bun interior. The heat is supplied and thebun 10 1B5 retained on the forming member 18 preferably fora period sufiicient to toast the walls ofthe cavity 15, thereby imparting crispness, improved taste and form retaining rigidity thereto. The bun 10 is thereupon re,- 18
